Thanks for the reply Mike.
Yes, I am able to boot 32 bit 2.6.38 kernel without tboot using the following
grub.cfg entry:
menuentry "Ubuntu, with Linux 2.6.38-020638-generic (on /dev/sda1)" { insmod
part_msdos insmod ext2 set root='(hd0,msdos1)' search --no-floppy
--fs-uuid --set 154e4bc5-aa94-4e1d-9f1c-e6c5cda3ed38 linux
/boot/vmlinuz-2.6.38-020638-generic
root=UUID=154e4bc5-aa94-4e1d-9f1c-e6c5cda3ed38 ro quiet splash initrd
/boot/initrd.img-2.6.38-020638-generic}
I don't believe that the ERRORCODE got assigned any value at all during the
tboot booting on 32 bit configuration. That's just being the log from last
successful tboot boot on 64 bit configuration.
The whole thing is strange because, I am able to boot with tboot on exact same
hardware configuration but using 64 bit Ubuntu dist and 64 bit kernel.
Anyway thanks again,CheersSansar

Hi Sansar,

I have a problem with booting with tboot on Ubuntu 10.10 (32 bit)/ Linux kernel
2.6.38 (32 bit). I succeeded booting on same hardware but on 64 bit Ubuntu
10.10 and 64 bit 2.6.38 kernel.
Now the problem is, TBOOT hangs on the screen on which I could see the
following, then I've to power down to boot again.... TBOOT: VMXOFF done for
cpu 1 TBOOT: cpu 1 is waking up, SIPI vector=9b000 TBOOT: VMXOFF done for
cpu 4 TBOOT: cpu 4 is waking up, SIPI vector=9b000 TBOOT: VMXOFF done for

xxx] hub 2-0:1.0 : cannot reset port 1 (err = - 19)...
Could somebody help me further on?
Thanks in advanceSansar Choinyambuu

I've the following set of hardware:Intel DQ57TM board (with q57 Chipset) and
Core i5 660 processor.I've updated my BIOS to the latest available version of
22.03.2011.I've enabled TPM, VT-d, TXT enabled in BIOS and taken ownership of
my TPM with well known passwords.
The following is the output I was able to get using tboot/utils/txt-stat after
power down and boot without tboot:
Intel(r) TXT Configuration Registers: STS: 0x00000002 senter_done: FALSE
sexit_done: TRUE mem_unlock: FALSE mem_config_lock: FALSE

slp_entry_error: FALSE secrets: FALSE block_mem:

It looks like the measured/verified lanuch succeeded based on this ERRORCODE.
The problem is further down the line. DIDVID: 0x0000001fa0008086

Following is the entry in my grub.cfg :
menuentry "Ubuntu, with Linux 2.6.38-020638-generic with tboot (on /dev/sda1)"
{ insmod part_msdos insmod ext2 set root='(hd0,msdos1)'
This line looks strange to me (I'm not saying it's wrong). My root device is
always ext2 not msdos and is set like this:
insmod ext2set root='(hd0,1)'
Are you able to boot your 32-bit kernel without tboot? What does that grub
menuentry look like?
Good luck,
-Mike
